1. Error text shows in red inside the desktop audio meter bar (scrollable) when TRAX load or playback fails — user gets feedback, not just a silent red dot. 2. LoadTrax no longer nulls _music on error — the track path is retained so the user sees what failed and can retry. 3. OnTraxPlaybackEnded now receives the NAudio exception and surfaces it. 4. TRAX dot is green (playing) or gray (idle/no track) — no more yellow or red states. 207 tests, 0 warnings.
ytLlive
A creator-proof live-streaming and recording app for YouTube — native Windows (C# / WPF / .NET 8).

Design Principle
This software is so intuitive that even the most right-brained person can easily intuit and use it.
Every feature is measured against this. One-click go-live, sane YouTube defaults, visual scene building, and no dead ends — every action has a visible outcome.
Why ytLlive
OBS treats YouTube as an afterthought; SLOBS is Twitch-first with YouTube bolted on. ytLlive is designed and dedicated to YouTube livestreaming and recording, and to YouTube's specific quirks.
Account Assumption
ytLlive assumes you already have a YouTube creator account — connecting uses "Sign in with Google" to link that existing account. ytLlive does not create accounts. If you don't have a YouTube channel yet, set one up on YouTube first, then connect it here.
